NuTone makes wireless chimes in both plug in and portable systems. With a plug-in system, the receiver is plugged into a wall outlet and the transmitter is installed outside the door. A basic model comes in white and features three-door operation. A strobe light version is useful in noisy environments or for the hearing impaired. When someone rings the doorbell, the light flashes to indicate arrival. Mechanical through-door greeters are also available, allowing the homeowner to see who is at the door.

Jacob Jensen makes systems that are truly works of art. Some feature contemporary, award-winning designs and include five polyphonic bell tones. Featured are a town hall bell, lounge tune, Asian tune, and wooden door knock. A special low-frequency tone is included for homeowners who are hearing impaired. The receiver can be used free standing or mounted to a wall and the transmitter may be screwed in or attached using double-sided tape.

Models from the basic to the designer are available from Heath/Zenith. For $15, consumers can find a wireless plug-in chime that features a two-note melody. An eight-note plug-in model is available for just under $20 and a contemporary solid birch and walnut wood system can be found for under $60. This attractive model features a two-note melody and adjustable volume control.

Wireless receiver bell is also available from numerous other manufacturers. Some people tire of replacing their faulty electrical chimes and instead choose to go wireless. Doing so does not involve much money or complicated installation. If the bell is working properly, adding a compatible wireless receiver on another floor allows the homeowner to hear the doorbell when a visitor arrives.
